Definitions
- the present invention relates to a method of producing a beta-glucan; use of a non-pathogenic saprophytic filamentous fungus or composition comprising it for providing a beta-glucan and thereby improving food structure, texture, stability or a combination thereof; use of a non-pathogenic saprophytic filamentous fungus for providing a beta-glucan and thereby providing nutrition; and use of a fungus or composition comprising it in the manufacture of a medicament or nutritional composition for the prevention or treatment of an immune disorder, tumour or microbial infection.
- Beta-glucans are made of a ⁇ - glucose which are linked by 1-3 or 1-6 bonds and have the following characteristics that are attractive to the food-industry: viscosifying, emulsifying, stabilising, cryoprotectant and immune-stimulating activities.
- fungi can produce high amounts of biopolymers (20 g/1) such as beta-glucans.
- biopolymers (20 g/1) such as beta-glucans.
- scleroglucan a polysaccharide produced by certain filamentous fungi (e.g. Sclerotinia,
- Corticiwn, and Stromatina species which, because of its physical characteristics, has been used as a lubricant and as a pressure-compensating material in oil drilling (Wang, Y., and B. Mc Neil. 1996. Scleroglucan. Critical Reviews in Biotechnology 16: 185-215).
- Scleroglucan consists of a ⁇ (l-3) linked glucose backbone with different degrees of ⁇ (l-6) glucose side groups. The presence of these side groups increases the solubility and prevents triple helix formation which, by consequence, decreases its ability to form gels.
- the viscosity of scleroglucan solutions shows high tolerance to pH (pH 1-11), temperature (constant between 10-90°C) and electrolyte change (e.g. 5% NaCl, 5% CaCl 2 ).
- electrolyte change e.g. 5% NaCl, 5% CaCl 2
- its applications in the food industry for bodying, suspending, coating and gelling agents have been suggested and strong immune stimulatory, anti-tumour and anti-microbial activities have been reported (Kulicke, W.-M., A. I. Lettau, and H. Thielking. 1997, Correlation between immunological activity, molar mass, and molecular structure of different (l ⁇ 3)- ⁇ -D-glu
- EPS filamentous fungi
- the fungal EPS could be incorporated into a health food (e.g. EPS as texturing fat replacer for low-calorie products or new immuno-stimulatory products) or provided alone for example as a food supplement.
- the present invention provides a method of producing a beta-glucan which comprises fermenting a suspension comprising a non-pathogenic saprophytic filamentous fungus and extracting a beta-glucan from the suspension.
- the present invention provides use of a non-pathogenic saprophytic filamentous fungus or composition comprising it for providing a
- SHEET RULE 26 beta-glucan and thereby enhancing food structure, texture, stability or a combination thereof.
- the invention provides use of a non-pathogenic saprophytic filamentous fungus or composition comprising it for providing a source of a beta-glucan and thereby providing nutrition.
- the invention provides use of a non-pathogenic saprophytic filamentous fungus or composition comprising it in the manufacture of a medicament or nutritional composition for the prevention or treatment of an immune disorder, tumour or microbial infection.
- an embodiment of a method of producing a beta-glucan comprises fermenting a non-pathogenic saprophytic filamentous fungus selected from the group which consists of Penicillium chermesinum, Penicillium ochrochloron, Rhizoctonia sp., Phoma sp., or a combination thereof. More preferably, at least three of these fungi are fermented together. More preferably all of these fungi are fermented together.
- an embodiment of a method of producing a beta-glucan comprises the step of fermenting for at least about 50 hours, more preferably about 80 hours to about 120 hours, even more preferably about 96 hours.
- a high yield of beta-glucan is produced.
- an embodiment of a method of producing a beta-glucan comprises the step of fermenting a suspension in a medium comprising a component selected from the group which consists of NaN0 3 , KH 2 P0 4 , MgS0 4 , KC1 and yeast extract. More preferably it comprises at least three of these components. Most preferably it comprises all of these components. It has been found that a medium having these components provides the advantage that a high yield of beta-glucan is produced.
- an embodiment of a method of producing beta-glucans comprises the step of cultivating the fungus in minimal medium.
- the medium comprises only glucose and salts and provides the advantage of enabling isolation of a highly pure polysaccharide at the expense of the production yield. This is because yeast extract contains polysaccharides that are difficult to separate from the EPS.
- the medium comprises NaN0 3 (10 mM), KH 2 P0 4 (1.5 g/1), MgS0 4 (0.5 g/1), KC1 (0.5), C 4 H 12 N 2 0 6 (10 mM) glucose (60) adjusted to pH 4.7.
- an embodiment of use of a fungus according to an aspect of the invention comprises use of a fungus selected from the group which consists of Penicillium chermesinum, Penicillium ochrochloron, Rhizoctonia sp., Phoma sp., or a combination thereof.
- a method of producing a beta-glucan comprises fermenting a suspension which comprises a fungus in a medium of (g/1) NaN0 3 (3), KH 2 P0 4 (1), MgS0 4 (0.5), KC1 (0.5), Yeast Extract (1.0), glucose (30) adjusted to pH 4.7.
- the fermentation is allowed to proceed for about 96 hours at about 28 °C with shaking at about 18rpm.
- strains which initially do not appear to produce polysaccharide are incubated for about 168 hours.
- Media TBl (g/1) was used as follows: NaN0 3 (3), KH 2 P0 4 (1), MgS0 4 (0.5), KC1 (0.5), Yeast Extract (1.0), glucose (30) adjusted to pH 4.7
- Fermentation time was 96 h at 28°C with shaking at 180 rpm.
- the incubation was prolonged to 168 h.
- Botritis cinerea P3 2.64 + 0.10 5.90 + 0.57 4.35 2.23
- Penicillium ochrochloron P45 10.53 ⁇ 2.87 0.45 + 0.07 3.50 0.04
- urea Besides sodium nitrate, other nitrogen sources such as urea, ammonium nitrate, ammonium phosphate and ammonium sulphate were used.
- urea EPS production by Rhizoctonia sp. P82 and Phoma sp. P98 reached the same levels obtained on sodium nitrate.
- EPS PURIFICATION AND CHARACTERIZATION The EPSs produced by Rhizoctonia sp. P82, Phoma sp. P98 and Penicillium chermesinum P28 were purified. The polysaccharides were exclusively constituted of sugars, thus indicating suprisingly high levels of purity. Both thin layer chromatography (TLC) and gas chromatography (GC) analysis showed that the EPSs from Rhizoctonia sp. P82 and Phoma sp. P98 were constituted of glucose only. In contrast, that from P. chermesinum P28 was constituted of galactose with traces of glucose.
- TLC thin layer chromatography
- GC gas chromatography
- the EPSs from Rhizoctonia sp. P82 and Phoma sp. P98 were subjected to in vitro and in vivo experiments.
- the purified EPSs were randomly broken in fragments of different molecular weights (from 1-10 to MO 4 Da) by sonication. The free glucose concentrations of the sonicated samples did not increase, thus indicating that no branches were broken.
- the experiments were carried out with EPSs at high MW (HMW, the native EPSs), mmeeddium MW (MMW, around 5-10 5 Da) and low MW (LMW, around 5-10 4 Da).
- Immuno-stimulatory action was evaluated in vitro by determining effect on TNF- ⁇ production, phagocytosis induction, lymphocytes proliferation and IL- 2 production.
- EPSs stimulated monocytes to produce TNF- ⁇ factor; its content increased with increased polysaccharide concentration and was maximum when medium and low MWs were used.
- mice Female mice were inoculated three times subcutaneously (SC) and/or orally (OR) with MMW EPS (2 mg/100 g weight) and Lactobacillus acidophilus (MO 8 cells/100 g weight) after 1, 8 and 28 days. Bleedings were carried out after 13 and 33 days. In vivo immuno-stimulation was evaluated by comparing antibody production by an ELISA test.
- mice that received OR bacteria showed no increase in their antibody content, regardless of their glucan inoculation. However, differences in antibody production were observed among mice inoculated SC with bacteria. Furthermore, antibody levels of mice that received SC only bacteria were significantly higher (P ⁇ 0.01, by Tukey Test) than those that had received glucan and bacteria both SC and glucan OR and bacteria SC.
- Rhizoctonia sp P82 is interesting in view of its short time required for fermentation, its high level of EPS production and its absence of ⁇ -glucanase activity during the EPS production phase.
- its EPS, as well as that from Phoma sp. P98 is a glucan characterised by ⁇ -1,3 and ⁇ -1,6 linkages.
- results relating to immuno-stimulatory effects of the glucan produced by Rhizoctonia sp. P82 indicate the possibility of a good stimulatory activity.
